• How to compare premises, iSCSI and storage NFS for VMware ESXi 5 with IO Analyzer?

  Hello

  I have 2 hosts ESXi 5.0 with a few virtual machines running. I would compare the IO throughput for my local storage, iSCSI and NFS vmware storage store. Can someone point me to the right direction? I read the documents and tutorials, but I'm not sure how to compare tests from these 3 options.

  I have a need to compare the following storage options.

  Local disk on the ESX host

  iSCSI on QNAP NAS device

  iSCSI on EMC e 3100

  NFS on QNAP NAS device

  NFS on EMC e 3100

  IOmeter seems to be good tool based on reading, but still not clear where to make changes to pass tests of storage to another.

  Thanks in advance,

  Sam

  If you use IO monitor, then you must simply vmotion the VMS to the data store for the device you want to test, and then run the test (and Records results).  Can vmotion for the following data store and repeat.

• Change of storage iSCSI IPs

  Hello

  We will be consolidating the 2 sites in one soon, and in the context of that we'll have the blades moving and storage iSCSI from one site to the other and re - IP them in the process.

  That's what I had in mind, please let me know if Miss me something:

  -Stop everything and moving equipment

  -Fuel storage iSCSI and re - IP

  -Power of blades and change their IPs

  (at this point all data warehouses and virtual machines on show them also inaccessible)

  -Add the IPs blade storage unit to allow access

  -In storage adapters / iSCSI / dynamic discovery, remove the old storage IPs and add new IPs, rescan storage

  Here, we should have our data storages and all VMs back on their show normal, that we should be good to start turning on VMs.

  Anything I missed? I did similar work a few times, but not in the last year or so, just wanted to do a validation test. We lack ESXi 4.6 build 1050704.

  Thank you

  If it worked very well, just as described above. I have to award points to myself :-)

  Thank you

• Questions about iSCSI and subnets

  IM planning on a deployment of 8 ESX servers connected to an array of iSCSI on double dedicated switches.

  1. 2 cards on each ESX host network is dedicated to iSCSI and VMware dependent ontraffic.
  2. SAN iSCSI target consists of two controllers with 2 uplinks of iscsi on each controller (4 total)
  3. The manufacturer of SAN is suggesting setting up of their SAN ports in separate subnets for higher throughput
  • For the sake of simplicity lets say assign 10.10.100.1 24 ports SAN 1 & 3 and 10.10.200.1 24-port SAN 2 & 4
  • On the side of ESX, a single iSCSI VMKernel address will be 10.10.100.2 and the other will be 10.10.200.2.

  My questions:

  1. do I have to enable trunking VLAN on the side of the switch so that the initiator 10.10.100.2 ESX failover to the port of SAN 10.10.200.1 and vice versa, because they are not in the same subnet and therefore not in the same VLAN?
  2. If this is the case, will trunking VLAN also solve the problem if we were to buy an identical iSCSI SAN on the road and 2 subnets more setup for controllers, but still only have two cards on the ESX Server.
  3. I would assign the 2nd ESX Server in this config with the same IP addresses as the first, or I re them with differnet IPs (but obviously still in the same subnet as the storage arrays), for example ESX 1 is 10.10.100.2 and ESX 2 would be 10.10.100.3

  Any other associated iSCSI I get with VMware, simply not able to think through this particular obsticle and I don't have the equipment to test it yet. Doesn't help that it's late in my part of the world and my brain power is depleting fast!

  Thank you!

  I mean really isolated network. No routing between them.

  Is the software of multiple paths that can pass a path to another, and if you need one network to another.

  Note that the PowerVault will have an interface of a mosquito net and to one another for each processor.

• All share storage iscsi connect same target and volume

  Hi Alls,

  I have openfiler and do 1 iscsi volume share in two ESX hosts with even described as iscsi target.

  So a (first) ESX have dynamic config discover iscsi target and the format of finishing, so ESX block size have new data store come from iscsi.

  Another ESX must sign in with the same ip address of the iscsi target and even target iqn. then discover iscsi and rescan datastore have see the name of name identical to that found on ESX first data store.

  (Note for second ESX is not block format size but rescan HBAS/VMSF found eponymous store data like first ESX)

  Issue.

  1. for iscsi target that have one objective and correspond to a volume on openfiler can operate with 2 ESXs at the same time with the same target?

  2 if not, how to configure shared storage with openfiler that can used data volume on openfiler?

  Kind regards

  Like I said before, vMotion can saturate an uplink, so you will need to keep an eye on it. If you want to perform vMotion on the same vSwitch anyway, I suggest you create a group of separate ports with private IP (e.g. 192.168.x.y) addresses for her and let the two active vmnic for this group of ports allow failover in the event of an uplink failure.

• Storage vMotion and RDM

  I have a question for you about storage vMotion. I have a virtual machine with a vmdk file and a RDM. I want to storage vmotion the vmdk file. There is also a file associated with the ROW pointer. How this pointer file is reassocie to the RDM? I'm evacuating small LUNS and move virtual machines to the largest lun.

  On page 199 and 201 of the basic ESX Administrator's Guide, it states that, if I select "same as Source for a RDM, only the mapping file will be migrated. Have you done this before? I just wanted to see if anyone in the field has had an experience with this process.

  7. If you chose to move the virtual machine configuration file and virtual disks, select a disc format, and then click

  Next.

  Description of the option

  Same as Source to use the format of the original virtual disk.

  If you select this option for a RDM in physical or virtual drive

  compatibility mode, only the mapping file is migrated.

  Thin provisioned using the format thin to save storage space. The thin virtual disk use as

  storage space because it needs for its initial implementation. When the virtual disk

  needs more space, it can grow in size up to its maximum allowed of capacity.

  This option is not available for RDM in physical compatibility mode. If you

  Select this option for a virtual RDM compatibility mode, the ROW is

  converted to a virtual disk. RDM converted virtual disks cannot be

  converted into RDM.

  Thick allocate an amount fixed disk space for the virtual disk. The virtual

  drive in thick format does not change its size and from the beginning

  occupies the entire data store space for her.

  This option is not available for RDM in physical compatibility mode. If you

  Select this option for a virtual RDM compatibility mode, the ROW is

  converted to a virtual disk. RDM converted virtual disks cannot be

  converted into RDM.

  Thank you

  Hi Savoy6,

  When you sVmotion a virtual machine with a disc RDM, the pointer file is re-created on the new location and points to the raw LUN.

  Take a look at this kb for more information.

• Activate a path dead redundant storage iSCSI

  I have a known issue between ESX 4 and EqualLogic iSCSI storage array. During periods of low i/o activity I lose my redundant path to some data for example stores

• WinXPsysytem: The upgrade and have questions

  Have a dell e521 that I train and some questions.  Have already updated to 3 GB of memory on x 86 operating system.  Bios version active what 1.1.6 4/7/2007.  Have checked Dells site and they offer a version of bios 1.1.11 released on 04/09/2007.  Having checked their previous versions and mine is not yet in there.  Don't know if I should go with the 1.1.11 version or stick with what is on mine, any suggestions?  Also, I put in a 500 GB seagate HDD.  Have a 80 GB drive there now which is pretty maxed out.  Playing with the idea to put xp pro on the 80 GB and using the programs and storage 500 GB.  I would like to know if it's a good idea or not!  Could use pointers and how much others who have more experience I have of course on my best options for installation.  for performance and features.  Thank you in advance, Ron.

  It's sad to say, you should probably have spent your money on a new computer rather than on the RAM and a new hard drive.  Windows XP (you posted in a forum of Windows XP, that's what I assume you have) will be supported is no longer starting in April 2014. This means no more security updates and therefore increases the vulnerability to malware.

  That said, your system now-updated can probably support Windows 7. You must run the Windows 7 Upgrade Advisor to check the remaining material.

  As you say, Dell does not list the intervening versions of BIOS with 1.1.4, 1.1.10, so unless someone at Dell or in the Dell forums can tell you what "improvements" in your version or with your version 1.1.10, you have no way of determining that. Based on omissions, I think there were only minor changes in these versions.

  Normally, I would leave the BIOS alone.  Note, however, that Dell "recommends" 1.1.10 be installed because
  The update contains improvements or changes that will keep your system current and compatible with other system modules (firmware, BIOS, drivers and software) software.
  If you want to stick with XP, I would leave the BIOS alone. If you want to install Windows 7 (assuming that there are Windows 7 drivers for all your hardware), I would Setup 1.1.11.  Be sure to read and follow instructions carefully.

  BTW, it's a little surprising that you only have a 80 GB drive.  CNET review of the Dimension E521 said he came with a 320 GB drive.

• How to configure and use the local storage dirve and usb

  My company bought a server DMM cisco as well as 10 players of 4310 g dmp.  I tried to work on mine here to get it all working.  Let me expose what we would do first before to get into the details.

  The cental DMM will it play any content and be used to create and manage the content here at company wehre I am.  However my boss wants to send dmp individual players (4310 g) out to our factories across the country.  He wants me to be able to creat content or allow a person managing the exact address to edit the content and then push the content from the server DMM to corporate local DPM record either on local storage or attached thumb order.  I guess my questions on what are the following.

  (1) is it necessary to push the content locally for playback?  Willingness to play the content of our dmm on the wan to do lots of traffic?  Presentations could be as simple as a welcome page based presentation playing images video and flash.

  (2) based on local content would be a wise decision I'll have to see exactly how this is done poorly.  In the settings of the dmp, I see the setting of local storage and turned it on and set to read/write.  In regard to the command of thumb gose exactly how I implement that so that DPM can see?  I plug to the back of the drive, and it seems that it is active but the management console of the player I don't see anyway to actaully see if she knows the USB.

  (3) how will push the content for local storage and control of the DMM thumb?  It looks like I can send things to the storage internal if package transfer and or advanced/DPM deployment tasks or server file.  What exactly is the difference between these two?

  (4) Lastly how I actually play the local content of the dmp?  Can I set this up on a schedule of the dmm just like I would if he played the local dmm?

  I searched through the documentation, but I have not found any good docs who are clear to actually how to do these things.  So, any help would be appreciated.

  Thanks in advance.

  Hi Glen,

  Here are the answers to your questions

  1) is it nessesary to push the content locally for playback?  Will  playing content from our dmm over the wan be to much traffic?   Presentations could be as simple as a basic welcome page to a  presentation playing video and flash images.

  It is not required to push the content locally, you can also play the DMM directly. The main advantage of playing on the spot, is that you can transfer the videos several hours or days before the presentation begins to be played if you deploy content off hours and then, when he's ready to start playing the new presentation.

  If you play directly the content of the DMM, the content will be transferred at the time of the DMP starts playback. This may fail if the WAN link is saturated at that time here.

  2) If pushing the content local would be a wise decision I am having  difficulty seeing exactly how this is done.  In the dmp settings I see  the local storage setting and have it turned on and set to read/write.   As far as the thumb drive gose how exactly to I set that up so the dmp  can see it?  I plug it in the back of the player and it looks like it's  active but from the management console of the player I do not see any  way to actaully see if it knows about the usb thumb drive.

  You don't need to do anything to enable USB storage, simply plug it in. To confirm that the DMP is able to see it properly, the simplest way is to connect to the DPM via FTP and confirm that he has a «usb_2» directory This "usb_2" directory, where is the USB drive is mapped.

  3) how will I push the content to the local storage and the thumb drive  from the DMM?  It looks like I can send things to the internal storage  though the advanced tasks/deployment package and or file transfer to DMP  or server.  What exactly is the differnce between these two?

  The task of "File transfer" will just do this, transfer a file to the DMP. The deployment package is smarter and will transfer all the contents of a presentation and organize them in a structure that can be used to read the content locally. You should always use the deployment package.

  4) finally how will I actually play the content from the local dmp?  Can  I set this up on a schedual from the dmm just like I would if it was  playing from the local dmm?

  Yes, she may be scheduled as any other presentation.

  I suggest you have a look at the link below. He explains the steps required to configure the deployment package and read the content deployed with it.

  http://www.Cisco.com/en/us/docs/video/digital_media_systems/5_x/5_2/DMM/user/guide/DMP/CDs.html#wp2188026

  I hope everything is clear now, but if you have any questions, let me know. I'll try to answer.

• Many storage spaces and data for each quarter of the year files

  Hello

  I am junior DBA and I have a question about tablespace partitioning or data file sharing.

  I have a database of 10g in many storage spaces, for example:

  KER_DATA_2009_Q1

  KER_DATA_2009_Q2

  KER_DATA_2009_Q3

  KER_DATA_2009_Q4

  KER_INDX_2009_Q1

  KER_INDX_2009_Q2

  KER_INDX_2009_Q3

  KER_INDX_2009_Q4

  There is also a data file for each tablespace that is mentioned.

  But for this year 2013, only two big storage space I can get one and data KER_DATA, KER_INDX files.

  All tables and indexes in the whole database are KER_DATA, KER_INDX, tablespaces.

  I don't know any cut in two storage spaces and means of data files. Is this something like tablespace partitioning? This can be done automatically or someone needed to do it manually on the end of each quarter?

  This should be done to improve performance, several small files data instead a large?

  Can some admin explain this to me?

  The reason for this separation of database/tablespace was partitioning. There are a lot of tables partitioned by date column, and there are partitions for each quarter of the year. There are tablespace with a data file for each quarter (partition).

• VMFS and VMDK compatibility

  Hello

  I have a number of ESX 3.0.2 - Update1 host I do fresh installs of ESXi 4.1 on. The 3.0.2 hosts are connected to the external storage where is stored the VM and data warehouses. ESXi 4.1 is compatible with the version in the format/VMFS and VMDK/version of the format of the existing data? Guests of ESXi 4.1 will be able to set up warehouses of data and power ok the virtual machine?

  George.

  There are two things to look at. The first is the version of the VMFS file system, which is - as you say - 3.21 VMFS, so it's ok. The second is version of virtual equipment of the virtual machine, which must be at least 4. (see http://kb.vmware.com/kb/1003746) With ESX 3.02, this should be the case.

• sVMotion between iscsi and fc?

  I would like to know if sVMotion worked between iscsi and fc storage.  Just by looking at the possibility of moving from FC to iscsi on the road and wanted to check, it is that we give a host at the same time we can use svmotion to get the virtual machine out of a store on a datastore iscsi and FC database.

  Ideally the VM perform during this process. Any witch hunt, it's if it was running?

  Storage VMotion does not care SAN type, I carried out all types of migration between FC, iSCSI and NFS myself.

  So don't worry about it. But beware this SVMotion create large extra i/o load, so run when it will not affect the services running.

• What to use for the storage media and backup?

  What material and components should I buy if I want to automatically back up our three Macs and watch downloaded (NOT continuous) movies on TV?

  Here is our current configuration:

  -Computers: (Mac Mini, MBP and Air)

  -Router/backup: via TimeCapsule (with our satellite Internet connected to the TimeCapsule via ethernet input)

  -Film/storage media: digital WD hard drive

  -J' have an Apple TV (3rd generation), but we do not use it... cannot

  We currently live in Kenya, where internet speed is not great... so we are unable to stream movies.  Average speed is about 100 Kbps.  Have about 2 TB of movies we watch currently on TV by plugging a portable hard disk into the DVD drive. I know enough that IT is dangerous (e.g. not much!), but need advice on options on a good way to potentially combine these requirements (storage backup and film). Potentially, something like a new RAID drive plugged into a router. RAID drive backups using Time Machine and then also has films on which can be wired (via the USB port? Ethernet to Apple TV 4th Gen to HDMI to TV?) TV to watch movies. Not sure if I need something like Plex media server or something to do, however.

  Thanks much for any help!

  I suggest that you consider a dedicated NAS device. An example would be the Synology DS416.

  Anything can be corrupted on your MacBook Pro, but from what you say, it seems that the cable drive/SSD/flash memory/SATA hard was seriously damaged. Him "question mark" means that your Mac is unable to find any bootable device, meaning that it does not yet detect your OS X drive.

  You should make a backup of your files (if you can still do it) and take the Mac at the Apple Store or dealer to get a diagnosis. There may be several damaged parts.

• Missing mass storage controller and keyboard filter driver

  I have a HP Pavilion dv5215us laptop that I just installed Windows 7.  I'm missing the drivers for the mass storage controller and keyboard filter.  I tried to download on the HP site, but it seems that there are no drivers for this computer/Windows 7.  Is there anything else I can do?

  What do these drivers?

  Thank you.

  Suggested by Paul drivers are compatible drivers the best suited. Please try them and let us know the status of the issue.
